Application filed April 2,1915. Serial No. 113,672.

'a compact, efficient and well-appearing hydrocarbon lantern in which the hydrocarbon fluid is forced to the burners by the pressure of air, from a suitable containing reservoir. v

The marked features of improvement to which the efiiciency and other desirable qualities of the lantern are due, will be fully described in the following specification and particularly pointed out in the subjoined claims.

The preferred form'of embodiment of my invention is illustrated in the accompanying drawings, of which Figure 1 is a front elevational view of the lantern, with the casing partly broken away to reveal the burner parts. Fig. 2 is a side mclevational view, partly broken away, of

the upper portion of the lantern. And Fig. 3-is a bottom plan view of the base of the upper portion of the lantern.

Throughout the specification and drawings, similar reference characters denote corresponding parts.

In a detailed description of the preferred form of embodiment of my invention, the

numeral 1 designates a chamber or reservoir adapted to contain kerosene or other hydrocarbon fluid. Provided on the top of the chamber 1 is an aininlet valve 2 suitable for connection to any common form of air-pressure pump by which air may be compressed above the fluid in the reservoir 1. Mounted upon, and communicating with the reservoir 1, is a short tubular standard 3 to which is secured a valve casing 4 for any suitable form of valve which may be controlled by a hand wheel 5 attached to a valve stem 6. Adapted to receive the upper threaded end of the valve casing 4-, is the lower contract with the lower ends of two supporting members and 11 through which the tube 7 also extends, are tightly compressed between a hexagon portion 12 on the upper end of said tube, and the coupling 8. The base pan 9 is provided with an annular horizontally disposed rim Or flange 13 to which is secured, at equal distances apart, a plurality of upwardly extending rods 1a which support an annular rim 15 having an upturned flange portion 16. Removably mounted on the rim 15 is a dome 17 having a raised hood 18 to provide between the latter and the dome, ventilating apertures 19. Suitably secured opposite each other, to the rim 15, are two upturned ears 20 which loosely receive, through apertures provided therein, the hook ends of a bail 21 by means of which the lantern may be readily carried from place to place;

Threaded into the upper end of the coupling 8, is a vaporizing tube 22 which is connected to, and supports a single casting preferably made of aluminum and comprising a mixing tube 23, air-inlet tube 2i, de-

pending burner tubes 25 and bracing arms 26. Projecting upwardly from the top of said casting, is a rod 27 whose upper threaded end loosely passes through an aperture in the top of the hood 18 to receive a nut 28 by means of which the dome 17 is held firmly upon the annular rim 15. By removing the nut 28, the dome 17 may be readily lifted from the rim 15, to permit the burner parts to be easily cleaned and new mantles applied.

Fitted tightly within the annular rim 15, and extending downwardly between the upright rods 11 to the base pan 9 upon which it rests, is a transparent globe 29. This globe is preferably constructed cylindrical in form, and may be made of glass or other transparent material.

In order to insure a. supply of pure air fo the mixing chamber, the air-inlet tube 2 is so constructed that each end thereof will project through and beyond a large circular apertur 30 provided in each side of the globe 29. This, therefore, brings the openings in said tube beyond the globe, whereby pure air from the outside may be drawn into the mixing chamber at all times.

For the purpose of properly bracing the burner parts within the lantern casing, the supporting members 10 and 11 heretofore in the base pan 9.

mentioned, are provided. The tube 7 passes through the lower ends of these members as hereinbefore described, whence they are large-headed pin 33 attached to said base pan near one edge of the opening 32, is a cover plate 34 which.may be moved to open and close said opening-by means of an. up-

turned edge Through this opening the mantles 3 6, which depend from the burner tubes '25, may be easily ignited without the neeessity' of removing the dome l7.

From thedbregning it will be observed that'l have provided asimple and eilicient hydrocarbon lantern" which produces awhite' light. of .constandpower and great bril- I liancy.

Having describedmy' invention, 1 claim: L Ina hydrocarbon lantern, a fluid reservoir, a tubular standard mounted thereon, a lantern frame, a base for said frame, a tubular imember extending upwardly from said standard andthrough' said base, a coupling removably secured to the upperend of said tubular member, hydrocarbon burner v -ineans secured to said coupling and communicating therethrough with thetubular member, and a shoulder 'on the'lower end of the latter, between which and the coupling the base is clamped, substantially as described.

Iivotally secured to a v menace 2. In a hydrocarbon lantern, a fluid reservoir, a tubular-standard mounted thereon, a lantern irame, a base for said frame, a threaded tubular member extending up wardly from said standard and through said base, a sleeve supported by the upper threaded end of said tubular member, a va- I porizing tube extending upwardly from said sleeve,.. hydrocarbon burner means supported upon said tube, and a shoulder on the lower end of the tubular member, between which and the sleeve the base is clamped,

substantially vas described.

3, In a hydrocarbon lantern, a "iuid' reservoir, a tubular standard mounted thereon, a lantern frame, a base, for said, frame,

, sleeve, a vaporizing tube extending" upv wardly from said sleeve, a m xing tube sup ported upon the vaporizing tube, a burner tube extending downwardly oneach side of 'said mixing tube, arms extending outwardly from the lower portions of said burner tubes, a tubular member extending from.

saidL sleeve, through said base into the tubul'ar standard, supporting members attached to said arms-through the lower ends of which said tubular member also passes,

said tubular member being threaded, and a shoulder on, the latter below said base, to compress the lower ends of said supporting members between the base and said con. filing, whereby said members may form a rm bracing, support for tie and burner ti1bes,;substantially as described In testimony whereof I have hereunto set my hand this 30th day of March, 1915.
